Crystal Structure and Photoluminescence Properties of Two Barium(II) MOFs
In this article, two Ba(II) metal-organic frameworks(MOFs), {[Ba(BPS)(H2O)2]·H2O} n(1) and [Ba(BPS)(H2O)2] n(2)(H2BPS=4,4′-bibenzoic acid-2,2′-sulfone), were synthesized and characterized. X-Ray crystal structural analyses reveal that compounds 1 and 2 have different structures, which is probably related to different coordination modes of ligand in compounds 1 and 2. It is remarkable that compounds 1 and 2 both show excellent thermal stability. The solid-state emission spectra reveal that compounds 1 and 2 both present strong luminescence emission bands at room temperature.
